Arcadia and Glidden, in the county of Carroll andState of Iowa, haveinvented a new l and useful Manure-Loader, of which the following is a specification.

The object of this invention is to provide` an improved mechanism for elevating and Aloading substances spread` or piled on the ground, such as manure.

Our invention consists in the construction,

arrangement and combination of elements hereinafter set forth, pointed out in our claims and illustrated by the accompanying drawing, in which- Figure 1 is a plan of the complete machine. Fig. 2 is a vertical section of the machine on the indicated line 2-2 of Fig. 1. Fig. 3 is a side elevation of thev machine. Fig. 4 is a plan of a portion of the machine taken onarline beneath the elevator thereof.

Fig. 5 is a detail elevation, on an 'enlarged scale, ofone member offeeding apparatus employed in the machine. Fig. 6 is a crosssection on the indicated line 6-6 of Fig. 5.

Fig.'7 is a cross-section on the indicatedline 7--7 of Fig. 5. Fig. S is a rear end eleva-- tion of the machine, dierin views in that the location and riving means of 'certain conveying mechanism are shown from other of modified formf In' the construction of the machine as shown, the numerals 10, 11 designate trac- 'tion wheels which carry an axle 12. A main frame 13 is mounted horizontally with its rear end portion supported on the axle 12.

'The forward end portion of the main frame is supported by and swiveled to a caster truck 14. tally on and transversely of the central portion of the main frame 13. A pulley 16 is mounted loosely onthe shaft 15 and operatively connected, as bya belt 17, to an engine shaft 18 of an engine 19 carried by the 'rear portion of the frame 13. A clutch member 20 is feathered to the shaft 15 and is adapted to engage the pulley 16 at times. The clutch member 20 may be moved longitudinally of the shaft 15 by a bell-crank lever. 21.ful crumed .on theframe 1 3.

The engine is run in such manneras to drive the up er portion of the belt 17 rearwardly as in icated by the arrow `a in Fig. 4. A bevel gear 22 is, mounted 'loosely on the' A shaft 15 is mounted horizonshaft 15 and a bevel gear '23 is mounted rigidly on a sleeve 24 on said shaft and is arranged opposite to the gear 22. A bevel gear 25 is mounted at right angles'to and vbetween Aand meshes with thel gems 22, 23. The gear 25 is journaled to the frame 13. The 'sleeve 24 is journale'd to the frame 13 and one end of the shaft 15 journals in said sleeve. A friction clutch 26 is feathered to the shaft 15 between and is adapted to connect said shaft to either of the two gears 22,

23 or to disconnect said shaft from said gears. A bar 27 loosely connects the friction clutch 26 with the frame 13. and may be moved laterally byy a hand lever 28 fulcrumedon said frame. The bevel gear'23 is connected, preferably by sprocket gearing 29 to the aXle 12.

When it is desired to advance the machine to the substance desired to be elevated and loaded into a wagon, the gear' 22 is clutched i to the shaft 15 and acts through the ear 25,

gear 23 and sprocket gearing 29 to onwardy rotation o the axle 12 and traction wheels 10 11. travel of the machine, the gear 23 is clutched to the 4shaft 15 and acts through the sprocket gearing 29 to reverse `the rotation of the axle 12 and traction wheels 10, 11, the gears 25 and 22 running lidly during such reverse movement.

An elevator frame 30 is provided and is en it is desired to reverse the supported at its rear upper end by stand` ards 31, 32 pivoted respectively to the. sidev of the frame 4and to the rear ends of the sides of the main frame 13 and bystandards 33, 34 similarly connecting the elevatorl oints inf advance a d through the elevator frame 30 `and is provided with pinions adapted to engage u said racks. AThe shaft 36 is connected, preferablyby s rocket gearing 37, to a crank 38 journale n one side of the frame 13. The crank 38 may be rotated manually and rotate theshaft 36l through the sprocket gearing 37. Rotation of the shaft36 in one' direction will cause the pinions thereon to climb the rack faces of the stirrups and raise the forward lowei: end portion of the elevator frame 30, the standards 31, 3 2 and '33, 34 articulatingon their pivotal connections of the elevator frame'.

v 39 also is supported and i with the frame 13 to permit such movement The crank 38 may be locked against rotation by 4any desired' means.

A drag conveyer 39 is mounted in the vframe and arranged for travel of its up-` per portion rearwardly and upwardly, as

-indicated by the arrow b in Fig. 2. The

' neath the frame 30 at the upper end of the drag conveyer 39, and a dehvery conveyer 46 is mounted for travel therein. The conyveyer 46 is carried by shafts 47, 48 journaled .in the frame 45. ,The shaft 47 is connected to the shaft 40, preferably by sprocket gearing 49,. and is driven thereby.

As illustrated in Fig. 8, a conveyer frame 45a may be arranged at right angles to the frame 30 andl contain a delivery conveyer on shafts 47a, 48a, the first of said shafts being connected to the shaft by 4bevel gearing 49a. A scraper blade 50 is mounted transversely of yand projects beyond the lowerforward end of t-he elevator frame 30` The scraper blade is inclined and has its rear upper margin overlapping the conveyer 39. .Bracket-s 51, 52 are fixed to and project upwardly from` central portions of are -mounted loosely-011 the shaft 53 andl the elevator frame 30 opposite each other and a rod 53 connects the upper ends of said brackets and extends across said frame. Bearings 54, in this instance four vin number,

project rearwardly therefrom. 'Rods 55, in this instance four in number, are mounted loosely through rearwardly.projecting portions of the bearings 54 and extend across the shaft 53. The upper end portions of the rods 55 are threaded to receive nuts 56 and rise from sldes of the elevator frame 30 and a shaft 611s journaled to said brackets and is con-V expansive'coil sprin s 57 are. mounted on said-rods between, an at their opposite ends impinge lsaid nuts and the bearings 54. Arms 58, in this instance four in number, are pivoted at their rear ends to the lower ends of the rods 55' and extend downward f and forward therefrom above the conveyer 39 and scraper blade 50. The arms 58 are spaced throughout the width of the conveyer 39. Brackets 59, are fixed to and the forward end portions of the nected, preferably by sprocket `gearing 62, to the outer end of the sleeve 24. The shaft 6l is formed wit-h a plurality of cranks, in this instance four in number,l set quartering relative to each other, between its bearings,

.arms 58- extend through `springs 57 ing-the tension of the arms 65.

and collar bearings 64, alsofour in number, are mounted 'loosely-on said cranks. The the collar bearings 64 beneath'and at rig t angles t-o the shaft 61. Extension arms 65, also four in number, are lmounted at their rear ends in andpivoted to thev collar bearings 64 and extend forward. and parallel with and above the arms 58 to points4 be ond the forward ends of the latter arms. okes 66, also four in number, extend beneath and embrace pairs of the arms 58, 65 adjacent to the forward endsof the first arms. End portions of the yoke 66 are threaded to receive nuts 67, 68. A bar washer 69 is mountedy on the arms of each yoke 66 and engages the upper surface of an arm 65. Expansive coil springs 70, 71 are mounted on the arms of the yokes 66 between and impinging the bar washer 69 and the nuts 67, 68 respectively. The spring-held-yokes 66 provide a resilient connection between the forward ends of the arms 58, 65 and said arms 65 may oscillate.

and articulate in the collar bearings 64. The arms 58, 65 preferably are com osed of tubing, and' gathering devices suc 1 as hoes 72, vor rakes, are mountedwith their stems n1 and fixed to the forward ends of said bars, the gathering devices, constructed either as hoes or rakes, or partly of one and artly of the other, depending at right ang es to and in front of the bars on which they are mounted. Q

It will be observed that the crank shaft 61 is rotated opposite to the shaft 40 and it is the function of said shaft 61 to oscillate the arms 58 and 65 and cause the gathering devices thereon to engage anddrag substances ,upon and across the :scraper blade 50 and upon the drag conveyer 39. The nuts 56 and provide means for adjusting the tension of the arms 58 and the nuts 67, 68 and springs 70, 71 provide means for adjust- Shoes 73, 74 are mounted adjustably on the forward ends of the sides of the elevator frame 30 and are adapted to slide on the surface of the ground and support the elevator frame relative thereto in advance of the caster truck 14.A v

In practical use the machine is advancedslowly and by its own power to the substance to be removed, suchas manure; the scraper blade 50 penetrates beneath the substance to be removed; the gathering devices 72, actuated by the arms on which they are mounted, engage and drag portions of the substance to be vremoved across the scraper blade 50 and upon the drag conveyer '39; the conveyer 39 carries the substance upwardly and 'rearwardly and deposlts 1t upon the conveyer 46; and the latter conveyer carries the substance to be removed and delivers the Asame to awagon dragged behind or driven alongside the motor-driven machine. When iso .the delivery conveyer is arranged as shown in Figsl, 2 and 3 it is necessary to bring the wagon in closeproxiinity to the frame 13, either by driving it laterally thereof or by attaching theypole of the wagon to said frame. We believe it to be preferable to arrange tliedelivei'y conveyer as shown in'Fig.
